Our Verdict

The Anker PowerCore 26800 is the power bank for serious travelers. At 26,800 mAh, it's the largest capacity allowed on flights (100Wh limit), and the 65W USB-C output charges a MacBook at full speed. Three ports mean you're charging everything at once.

What We Love

  • Maximum carry-on-legal capacity (26,800 mAh)
  • 65W USB-C charges MacBook at full speed
  • Three ports — charge multiple devices simultaneously
  • Anker's legendary reliability
  • LED charge indicator

Watch Out For

  • Heavy at 1.5 lbs
  • Slow to recharge itself (6+ hours)
  • Bulky for smaller bags

Long-haul travel is a battery killer. Between the phone, laptop, earbuds, and e-reader, you can drain everything before you land. The Anker PowerCore 26800 is the solution — maximum legal capacity in a reliable, well-built package.

The 26,800 mAh capacity is the maximum allowed on commercial flights (the FAA limit is 100Wh, and this pack comes in at 99Wh). It'll charge an iPhone 15 Pro about 6 times, a MacBook Air once, and still have juice left for your AirPods.

The 65W USB-C port is the headline feature. Most power banks top out at 18–20W, which charges a MacBook painfully slowly. The PowerCore 26800's 65W output charges a MacBook Air at the same speed as the wall adapter.

The main trade-off is weight. At 1.5 lbs, this is a substantial addition to your bag. If you only need to top up a phone, the Anker PowerCore Slim 10000 (0.5 lbs) is a better choice. But for laptop-dependent travelers, the PowerCore 26800 is worth every ounce.
